Awesome, cool, great, good, well done. An alien slang from the Steven Spielberg series "Invasion America" that aired on The WB in 1998. This origin influenced the usage of the word in the later WB cartoon series, Batman Beyond, and even later in the more recent incarnation of The WB, The CW's "The Flash" series.

The term is often used by the character Cisco, as he is an avid science fiction fan and Spielberg buff.
